LGBT mathematicians refer to individuals within the field of mathematics who identify as part of the LGBTQ+ community—encompassing lesbian, gay, bisexual, transgender, queer, and other sexual and gender minorities. Like in other fields, LGBT mathematicians have made significant contributions to mathematics, research, and education, although their experiences may have been shaped by the challenges and discrimination often faced by marginalized groups.

Fictional mathematicians are characters in literature, film, television, and other forms of storytelling who are depicted as mathematicians, mathematicians' assistants, or individuals deeply involved in mathematical concepts. These characters may be central to the plot or serve as supporting roles, and their mathematical pursuits can range from abstract theory to practical problem-solving.

The Fellows of the American Mathematical Society (AMS) is an honorary program that recognizes members of the American Mathematical Society who have made notable contributions to the advancement of mathematics. Established in 2012, the program honors individuals for their exceptional achievements in research, education, and service to the mathematical community. Selection as a Fellow of the AMS is based on nominations and includes criteria such as outstanding contributions to the mathematical sciences and a sustained record of research and scholarship that has significant impact.

Cultural depictions of mathematicians often reflect a range of stereotypes, themes, and representations in literature, film, television, and other forms of art. These depictions can vary significantly from positive portrayals to negative stereotypes. Here are some common themes and characteristics associated with cultural depictions of mathematicians: 1. **The "Mad Scientist" Trope**: In some works, mathematicians are portrayed as eccentric geniuses, often obsessed with their work to the point of social awkwardness.

Amateur mathematicians are individuals who engage in mathematical activities, research, or problem-solving out of personal interest and passion rather than as a professional mathematician. They may not have formal training or qualifications in mathematics, but they often pursue mathematical ideas, concepts, and problems independently or within informal communities. Amateur mathematicians have historically contributed to various areas of mathematics, sometimes making significant discoveries or advancements.

"African mathematicians" refers to mathematicians from the African continent or those of African descent who have made significant contributions to the field of mathematics. This term encompasses a vast array of individuals across different countries, cultures, and historical periods.

In geometry, a "tomahawk" typically refers to a shape or figure resembling the outline or silhouette of a tomahawk, which is a type of axe. However, there isn't a widely recognized geometric term specifically called "tomahawk" in classical geometry.

A tally stick is a historical accounting tool used primarily in England and other parts of Europe during the medieval period. Typically made from wood, a tally stick is a stick with notches carved into it to represent numbers or amounts. The most common use of tally sticks was for recording debts or financial transactions. The process of using a tally stick involved cutting the stick to a specific length and making notches on it to indicate amounts owed or other data.

Straightedge can refer to a few different concepts, depending on the context: 1. **Tool**: In carpentry and various trades, a straightedge is a tool used to create straight lines or check the flatness of a surface. It is typically a long, flat piece of material, usually wood or metal, marked with measurement units and utilized for drawing or guiding cutting tools.

A planimeter is a measuring instrument used to determine the area of a two-dimensional shape, particularly in fields such as engineering, architecture, and cartography. It works by tracing the perimeter of a figure, allowing the instrument to calculate its area based on the path traced. There are two main types of planimeters: 1. **Mechanical planimeters**: These are typically made of metal and consist of a movable arm attached to a fixed base.

A mathematical instrument is a tool or device used to aid in the measurement, calculation, visualization, or analysis of mathematical concepts or problems. These instruments can range from simple hand-held tools to complex electronic devices. Here are a few categories and examples of mathematical instruments: 1. **Measuring Tools**: Instruments used for measuring lengths, angles, areas, or volumes.

The term "Integrator" can refer to several different concepts depending on the context in which it is used. Here are a few interpretations: 1. **Mathematics**: In mathematics, an "integrator" often refers to a function or operator that performs integration, which is the process of finding the integral of a function.

Intergraph, now known as Hexagon Geospatial, is a company that specializes in geospatial software and technology. It provides solutions for geographic information systems (GIS), computer-aided design (CAD), and various applications in industries such as public safety, natural resources, utilities, and government.

A French curve is a template made from plastic or other materials, used in drafting and drawing to create smooth curves. It features a variety of curves along its edge, allowing artists, engineers, and designers to draw arcs and curves of different radii accurately. French curves are especially useful for freehand drawing and for creating complex shapes that cannot be easily achieved with a compass or straightedge. They are commonly used in technical drawing, illustration, and other fields requiring precise curvilinear designs.
